Is there any way to create the dynamic query on the custom setting. How?

Yes you can create dynamic query on custom setting .

`public List getCustomSettingList(String customSettingName,List FieldList){
if(FieldList.size()==0)
return null;
String soqlQuery = ‘SELECT ‘;
for(String field:FieldList){
soqlQuery+=field;
}
soqlQuery+’ FROM ‘+customSettingName;
return Database.query(soqlQuery);
}`
